Paper Abstract

In a wide region of incident angles between -60° and +70°, the self-pumped phase conjugate (SPPC) reflectivities (ri) that are greater than 60% have-been obtained in 45°-cut Ce:BaTiO3 crystal at X=5 l4nm. The SPPC buildup time was 3 sec. . A systematic study was undertaken to assess the i with respect to external angle of incidence (0) and the position (x) of the incident beam upon the crystal entrance face. We have been compared the photorefractive performance of this special 45°-cut crystal of Ce:BaTiO3 with the 0°-cut and 45°-cut BaTiO3 as well as the 0°-cut Ce:BaTiO3 crystal. Intentional doping with cerium has an important effect on the efficiency, sensitivity and spectral response of photorefractive effect. The 45°-cut Ce:BaTiO3 is sufficiently improved its photorefractive phase conjugate performance. keyword: self-pumped phase conjugation, Ce:BaTiO3 crystal
